Is Google Voice a Phone Company?

The FCC Asks Questions About Google Voice

Google Voice, the Internet voice application that functions similarly to a phone, blurs the line between the two forms of communication. Is it the same as phone service? Google says no, but a claim from telephone provider AT&T says it is. Now the Federal Communications Commission is on the case.

Last week, the FCC sent a letter to Google, asking them to explain how Google Voice works. The main reason? The FCC is trying to discern whether or not the app should be considered a phone service, subjecting it to more stringent regulations and fees.
